A video posted to Facebook over the weekend has gone viral and helped Las Vegas Metro Police catch a thief. The video shows a woman inside the Teriyaki Madness restaurant near Decatur and the 215. She asks the cashier if she could try a sample of the beef. When the cashier turns around, the woman is seen taking the tip jar off the counter and putting it in her purse and walking out. Dean Clarino, owner of the restaurant posted the video to Facebook, where it was viewed more than 3-million times.
